mb/google/bluey/mica: Add TPM I2C and EC SPI configuration

Browse source 
Communication with GSC and EC is abnormal because Mica is
missing the following configurations: DRIVER_TPM_I2C_BUS,
EC_GOOGLE_CHROMEEC_SPI_BUS,and MAINBOARD_GPIO_PIN_FOR_GSC_AP_INTERRUPT.

BUG=b:489062509,b:489264026
TEST=build mica board, flash to Quenbi to verify the GSC and
EC communication functionality.
Check if there are any further abnormalities in the bootup log:
For GSC:
Probing TPM I2C: Cr50 TPM IRQ timeout!
For EC:
crosec_spi_io: Timeout waiting for framing byte.
